Shure AD4QUS Digital Four-Channel Wireless Receiver

Product Overview

The Shure AD4QUS is a four-channel Axient Digital wireless receiver in a single 1U rack unit, packaged with cable and mounting accessories for complete out-of-box installation. It delivers transparent digital audio with true four-channel diversity reception, Dante audio networking, and High Density (HD) mode for maximum spectral efficiency in demanding commercial AV and broadcast environments. The AD4QUS suits initial installations where all required rack hardware, cabling, and mounting accessories are needed as part of a complete deployment. With a tuning range up to 184 MHz and compatibility with all Axient Digital AD and ADX series transmitters, it anchors scalable wireless systems in auditoriums, government facilities, broadcast studios, and large corporate campuses.

Product Description

The AD4QUS provides four channels of Axient Digital reception in a rack-ready package complete with accessories, making it the preferred purchase for greenfield commercial AV wireless installations. Its High Density mode enables deploying more simultaneous channels within a limited spectrum allocation—a practical necessity in convention centers, multi-room corporate facilities, and broadcast environments where spectrum is congested. Dante audio networking integrates directly into IP-based AV infrastructure, and a 4-port configurable Ethernet switch supports redundant audio distribution for high-availability deployments. AES67 and AES3 digital outputs ensure compatibility with broadcast consoles and professional DSP platforms. A front-panel headphone jack provides Dante Cue and Dante Browse monitoring for in-rack diagnostics. Full remote management is available through Wireless Workbench 6 and ShurePlus Channels. For the no-accessories variant, see the Shure AD4Q-NP; for a two-channel option, see the Shure AD4DNP.

Frequently Asked Questions

What accessories are included with the AD4QUS?
The AD4QUS US kit includes cable and mounting accessories required for rack installation. This makes it the preferred option for new deployments where no existing rack hardware is in place.

How does the AD4QUS differ from the AD4Q-NP?
Both receivers offer identical RF and audio performance with four channels of Axient Digital reception. The AD4QUS includes accessories for a complete initial installation; the AD4Q-NP ships without accessories and is suited for expanding existing systems.

Does the AD4QUS support Dante audio networking?
Yes. Integrated Dante audio networking allows distribution of all four audio channels over standard IP infrastructure. AES67 and AES3 outputs are also available for broadcast and installed AV integration.

What is the installation rack space requirement?
The AD4QUS occupies a single rack unit (1U), providing four channels of wireless reception in a compact, space-efficient form factor suited for system racks in corporate AV, broadcast, and government installations.

Can the AD4QUS be monitored and managed over a network without physical access?
Yes. Wireless Workbench 6 software and the ShurePlus Channels iOS app provide full remote management over a standard IP network, including frequency coordination, RF monitoring, and audio level control.
